images. We are motivated by a need to further research the idea of the chi-square attack.
The new method simply use the first-order statistics of DCT coefficients, but is more powerful
to detect the random embedding in JPEG images. For evaluation, we used versions of Jsteg
and Jphide with randomized embedding path to generate stego images in our experiments.
In results, the proposed method outperforms the method of Zhang and Ping and is …
